Phono Preamp Reviews

Trickle-down technology is a grand thing. It's comparatively easy to build an exceptional audio component when there are no constraints on technology, cost, user-friendliness, or lack thereof, but top designers are now packing more and more of the excellence of damn-the-torpedoes components into more affordable and accessible packages. Which brings us to the Aesthetix Rhea, a tubed phono preamplifier of exceptionally distinguished lineage.

CH Precision's P1 phono preamplifier, which I wrote about in the April 2017 issue, is not going back to its manufacturer. The longer I used it, the more obvious it became that I couldn't part with it, even though I said I couldn't afford it. The cost was stiff even at the accommodation price (at retail, the CH Precision P1 and its optional X1 power supply are $31,000 and $17,000, respectively, footnote 1), but I decided I could afford it, and bought it for myself as a 70th-birthday present. No, I can't hear as well as I did 30 years ago, but my listening is better than ever.

Among the electrically connected, the phrase short circuit induces panic and horrific images of tripped breakers, blown fuses, acrid blue smoke, and melted circuit boards. Nonetheless, near short circuits are becoming popular among the analog set. Moving-coil cartridges of an inductance and impedance so low they're nearly short circuits are now more common, thanks to powerful neodymium magnets that help produce more and more electrical output from fewer and fewer turns of coil wire. Perhaps the most extreme example of this is the Haniwa HCTR01 Mk.II cartridge, which has an internal impedance of 0.4 ohm and an inductance of 0.3µH.

Lately, there's been too much gear worth covering and not enough space to cover it in. So this time . . . less think-piece filler and more hardware!

Following my auditioning of Channel D's Lino 2C current-mode phono preamplifier, back in the world of voltage amplification, here's another phono preamp from another company based, like Channel D, in New Jersey. Probably not since Dynaco manufactured its electronics in Pennsauken has the Garden State enjoyed such riches of analog electronics!

Since acquiring SME in late 2016, Ajay Shirke's Cadence Group has moved cautiously. First, it revamped and cleaned up the company's somewhat chaotic worldwide distribution. More recently, the new owners eliminated from the bottom of the line the SME Model 10 turntable, introduced in 2000.
